Incredible Story Of The Earth


Incredible Story Of The Earth
Today, science has revealed much about our planet, from how it formed and has evolved over billions of years through to its current position in the universe. Indeed, right now we have a clearer picture of Earth than ever before. And what a terrifying and improbable picture it is. A massive spherical body of metal, rock, liquid and gas suspended perilously within a vast void by an invisible, binding force. It is a body that rotates continuously, is tilted on an axis by 23 degrees and orbits once every 365.256 solar days around a flaming ball of hydrogen 150 million kilometres (93 million miles) away. It is a celestial object that, on face value, is mind-bendingly unlikely.

As a result, the truth about our planet and its history eluded humans for thousands of years. Naturally, as beings that like to know the answers to how and why, we have come up with many ways to fill in the gaps. The Earth was flat; the Earth was the centre of the universe; and, of course, all manner of complex and fiercely defended beliefs about creation. But then in retrospect, who could have ever guessed that our planet formed from specks of dust and mineral grains in a cooling gas cloud of a solar nebula? That the spherical Earth consists of a series of fluid elemental layers and plates around an iron-rich molten core? Or that our world is over 4.5 billion years old and counting? Only some of the brightest minds over many millennia could grant an insight into these geological realities. While Earth may only be the fifth biggest planet in our Solar System, it is by far the most awe-inspiring. Perhaps most impressive of all, it’s still reaffirming the fundamental laws that have governed the universe ever since the Big Bang. Here, we celebrate our world in all its glory, charting its journey from the origins right up to the present and what lies ahead.
